Another TAP question : upgrade at airport
Sorry for a guy with 2000+ posts you'd think I'd have a better clue but getting info out of TAP is like pulling teeth.
So online there is an offer to upgrade...it has a minimum amount which is a little higher than i would like to pay.
My question is in the past have those of you who have upgraded at the airport did the cost to u/g go up or down or just stay the same as what was offered prior to the flight in the link with your itinerary?
Thanks again.
